Pseudo-Caster, 25mm (High)

Used as a caster-wheel (or caster-ball) for small robots. Product features no moving parts and simple #8 screw mount. In practice compact ball bearing style caster-wheels often drag and stick. The are expensive, complex, heavy and can rust if used in wet environments.

Our Pseudo-Caster (false-caster) design is free from any of the typical caster ball product drawbacks. Our design utilises a low coefficient of friction to offer a brilliant compromise between simplicity and rolling resistance (when printed from ABS or PLA).

Product Description

Model type: Multiple part assembly

STLhive 3D printing Product Feature/Benefits:

  • Print orientation (As shown) is intended to maximise part strength but may require more support material. Reorientation of the part may result in less required support material but may dangerously weaken the part resulting in the part breaking while in use.
  • This is an original STLhive design. It is specifically designed for 3D printing and is not available from anywhere other than

Additional items required:

  • To assemble you will need 1 screws not included (#8, Pan-Head, 1/2″ to 5/8″ Long – or Equivalent).
  • None

Additional fabrication required:

  • Typical removal of support material if Reqd.
  • Drill printed holes to full internal diameter if Reqd.

Purchasing / Downloading:

  • When you buy this part, you get “.STL” files in a “Zipped” folder (For Windows).


  • STLhive’s recommended printing suggestions are determined based upon the part’s usage. Safety is out main concern.
  • Alternate orientations may provide prints that use less support material but you do so at your own risk. We try whenever possible to orient the grain structure to maximize part strength.
  • This part is intended to be printed using high quality printers; and is modeled with great attention to detail. Printing quality is determined by the printer you are using, your printer set-up and by the type and quality of material used.
  • Filament based printers (like Makerbot and RepRap) may struggle to provide a part that is easily freed from support material.
